Taw qhia
Transistors yog cov neeg ua haujlwm ntawm cov khoom siv hluav taws xob niaj hnub no, tsim cov tsev thaiv ntawm suav tsis txheeb. Tab sis koj puas paub qhov kev hloov kho yooj yim tuaj yeem qhib cov haujlwm tshiab hauv cov khoom siv ntau yam no? Nkag mus rau diode-txuas transistor, cov txheej txheem ntse uas nthuav dav lub peev xwm ntawm cov transistor yooj yim. Cov ntawv tshaj tawm blog no dhia mus rau hauv lub ntiaj teb ntawm diode-txuas transistors, piav qhia lawv lub tswv yim, kev ua haujlwm, thiab qee qhov kev siv xav tsis thoob hauv hluav taws xob circuits.
Nkag siab txog Diode-Connected Transistor
Xav txog ib qho kev sib tshuam bipolar transistor (BJT). Nws muaj peb terminals: puag, collector, thiab emitter. Nyob rau hauv tus txheej txheem configuration, thov voltage rau lub hauv paus tswj cov tam sim no ntws ntawm collector thiab emitter. Txawm li cas los xij, hauv diode-txuas transistor, lub hauv paus thiab cov khoom sib txuas tau txuas nrog sab hauv lossis sab nraud, qhov tseem ceeb tsim ib lub davhlau ya nyob twg. Qhov kev hloov kho yooj yim no hloov pauv lub transistor mus rau hauv qhov hluav taws xob tswj qhov hluav taws xob, qhov twg cov hluav taws xob siv hluav taws xob mus rau qhov seem emitter davhlau ya nyob twg txiav txim siab qhov tsis kam.
Nws Ua Haujlwm Li Cas?
Nrog lub hauv paus thiab cov khoom sib koom ua ke, lub transistor ua haujlwm nyob rau hauv qhov hu ua rau pem hauv ntej-kev tsis ncaj ncees cheeb tsam. Thaum ib tug voltage yog siv rau lub emitter, tam sim no pib ntws. Txawm li cas los xij, tsis zoo li tus qauv transistor, qhov tam sim no tsis yog amplified. Hloov chaw, qhov kev tawm tsam ntawm lub emitter thiab lub hauv paus-collector davhlau ya nyob twg hloov pauv raws li qhov siv hluav taws xob. Qhov kev hloov pauv no tso cai rau cov ntawv thov zoo siab hauv hluav taws xob circuits.
Unleashing the Potential: Applications of Diode-Connected Transistors
Lub peev xwm los tswj tsis kam nrog voltage qhib qhov rooj rau ntau yam haujlwm:
Daim iav tam sim no: Cov khoom siv hluav taws xob zoo no siv cov diode-txuas transistors los tsim cov qauv zoo ntawm cov khoom siv tam sim no. Qhov no yog qhov tseem ceeb hauv cov ntawv thov xws li kev ua lag luam analog teeb liab thiab kev tsim hluav taws xob sib xyaw.
Theem Shifters: Qee zaum, hluav taws xob circuits ua haujlwm ntawm qib sib txawv. Diode-connected transistors tuaj yeem siv los hloov lub teeb liab hluav taws xob mus rau qib sib txawv, ua kom muaj kev sib raug zoo ntawm cov khoom.
Temperature Compensation: Qee yam khoom siv hluav taws xob tuaj yeem nkag siab rau qhov kub thiab txias. Diode-connected transistors tuaj yeem siv los them rau cov kev hloov pauv no los ntawm kev kho qhov tsis kam txais.
Xaus
Lub diode-txuas transistor tej zaum yuav zoo li ib qho kev hloov kho yooj yim, tab sis nws qhib lub ntiaj teb ntawm kev muaj peev xwm hauv kev tsim hluav taws xob hluav taws xob. Los ntawm kev nkag siab tias nws ua haujlwm li cas thiab nws cov kev siv ntau yam, koj tau txais kev txaus siab ntau dua rau kev siv ntau yam ntawm transistors thiab lawv lub luag haujlwm hauv kev tsim cov thev naus laus zis niaj hnub. Nrhiav kom nthuav koj cov kev paub ntawm cov khoom siv hluav taws xob thiab kev tsim hluav taws xob? Tshawb nrhiav peb cov peev txheej thiab cov lus qhia!
